Jandy Aquapure Ei - output fault?

I recently developed an "output fault" on my salt chlorinator. Any ideas? Jandy/Zodiac claims that because I got 7 years out of it, it needs to be replaced. I disagree. Power is there, I can't get past the error.

Welcome to TFP! Good to have you here :)

It's fair to say that it's normal to replace the chlorinator cell when it reaches the end of its lifespan. The 'cell' (or sometimes 'electrode') is the the assembly inside the clear housing, with the blades, where the chlorine is made, the part that can be cleaned.

7 years is a pretty good run on a salt water chlorinator cell. It's part no. 3 in this manual: https://www.jandy.com/~/media/zodiac/global/downloads/h/h0331400.pdf

I have the same "Output Fault" issue on Jandy Aquapure EI 35. Can the Salt Cell cause that message or just an Electrical issue where I would need to replace part R0512100 or R0512300?
